Merlin may be new,
but the team is not. . .

We’ve been building discovery and compliance software since the nineties.

About Merlin

Merlin Digital Magic is a secure cloud software technology company, formed by a legal technology pioneer and his longstanding  team of  designers, developers and operations professionals.

We got our start in the mid-1990s as part of a national law firm. It was there that our founder, John Tredennick, famously built litigation and compliance systems for the firm’s clients. Over the years, we were featured in videos by Adobe and Microsoft, were written about in scores of legal articles, won a number of innovation awards and, ultimately, were inducted into the Smithsonian Institute for our groundbreaking work developing litigation workflow software.

In 2000, the Tredennick team spun out of the law firm to form Catalyst Repository Systems, a pioneering e-discovery and compliance technology company. Over the next two decades, Catalyst grew to more than 160 people and five data centers, hosting software for many of the largest companies and law firms in the world. In early 2019, Catalyst was sold to a large public technology company.

Not ready to retire, John Tredennick founded Merlin later in 2019,  joined by a number of his previous team members. This time we get to start fresh, scrapping twenty years of legacy code in favor of building software using the latest and greatest technology and delivering it securely over the AWS cloud. We are passionate about reinventing search and building the best systems in the world for investigations, discovery and compliance.

Digital Magic

In the days of Camelot, Merlin conjured magic for King Arthur and his knights of the roundtable. While the magic seemed real, it was just a combination of chemistry and knowhow. 

Software is the magic of the 21st century. When we talk with Siri or use the Internet to get directions, it feels like magic when, in fact, it’s just well-written code. That’s Digital Magic.

From our Founder

I founded Merlin after 20 years as a trial lawyer and partner of a large national law firm, and another 20 as founder and CEO of an international legal software company. During those years, we built dozens of sophisticated software systems for major companies and law firms, along with the best AI-enabled discovery platform in the world. Automation, efficiency and service  were our watchwords.

Today, our mission is to use AI, open source, cloud computing and other digital magic to make search smarter, review faster, and compliance more affordable. Our goal is to help people quickly and easily find relevant information for investigations, discovery and regulatory compliance—without having to master complex search syntax

We are passionate about building the next generation of AI-Powered search, review and compliance software and delivering our systems securely from the cloud.
